When UAVs approach each other, the airflow affects their flight performance. This paper describes the interaction between two UAVs when two UAVs are close to each other in the vertical direction. In this paper, the proximity flight is imitated with fixed UAVs and the forces applied to the UAVs are measured at different distances between the UAVs. The experimental results show that the thrust of the lower UAV decreases due to the airflow from the upper side, which can be explained using the momentum theorem. The result can be helpful in determining the safer flight operation in narrow areas such as urban sites.
